5.9.3 Adjusting the squeegee
Angle Adjustment
The angle adjustment is the decisive
factor in ensuring that the sealing strips
on the squeegee lie evenly on the floor.
1. Park the machine on a level surface
and lower the squeegee.
2. Loosen the counternut on the adjust-
ing screw (Fig. 15/6) and adjust the
squeegee using the adjusting screw
so that the ends of the sealing strips
still have contact with the floor.
Figure A
Turn the adjusting screw counter-
clockwise: The clearance between
sealing strip and floor is reduced in
the centre.
Figure B
Turn the adjusting screw clockwise:
The clearance between sealing strip
and floor is increased in the centre.
3. Switch the machine on and check
the suction pattern. When the ma-
chine is in operation, the entire sur-
face of the sealing strips (centre and
outer areas) must be applied as
evenly as possible.
4. Tighten the counternut on the adjust-
ing screw at 5 lb ft.
